DESCRIPTION OF BIOLOGIC DUOFLOW SYSTEM SYSTEM OVERVIEW
2-6
2.2 WORKSTATION
The Workstation contains the following:
• Dual pumpheads, each consists of two biocompatible dual piston pumpheads. A built-in pressure
transducer is located on the workstation at the pump outlet. The pressure transducer measures
system pressure, which is displayed on the lower status bar of the software Manual and Run
screens. Purge and Pause buttons (Purge A, Purge B, and Pause) are present on the front of the
Workstation.
There are two types of pumpheads; the F10 and the F40. All DuoFlow systems have F10
pumpheads, except DuoFlow Maximizer 80 and DuoFlow Pathfinder 80 systems that have F40
pumps.
F10 and F40 pumphead kits are available to easily convert an F10 Workstation to F40 and vise versa.
(See Section 2.9.7)

• The Workstation houses the control circuitry for the Workstation pumps, MX-1 mixer, UV detector,
Conductivity monitor, and system valves (low pressure solenoid and automated high pressure inject
and select valves). Connectors on the rear panel provide inputs for valves and detectors, as well as
output to a chart recorder for UV and conductivity data at 1 V Full Scale and pen up/down, start/stop
control.
If a Maximizer is being used, connect devices to it to connect the mixer, Conductivity monitor, and
pH monitor to it, rather than to the Workstation.
• An AUX combicon connector used for (a) controlling fraction advances of the Model 2110 and
generic fraction collectors, (b) receiving an open/closed signal from a device such as a manual inject
valve, and (c) starting and stopping the Model EP-1 Econo pump for sample loading.
If a Maximizer is being used, connect these devices to its AUX connector, rather than to the
Workstation.
• Power supply for the Workstation electronics as well as all devices connected to and controlled by
the Workstation.
• Output power connectors to the UV lamp and a Model 1327 chart recorder.
• Two instrument bus (phone-type) connectors.
